Salgesic is a topical analgesic that typically contains active ingredients such as menthol or salicylic acid, used to relieve pain and reduce inflammation in conditions like Arthritis or muscle strains. It works by providing a cooling or warming sensation on the skin, which helps to distract from pain signals. Salgesic products are often available in the form of creams, gels, or patches. Always follow the usage instructions and consult a healthcare professional if you have any concerns.
